Serial No. 377,215.

This invention relates to new and useful improvements in shower-baths in which two or moreshowers are supplied withhot'and cold water from common hot and cold water chambers, respectively, the supply being regulated by means of appropriate valves. The form of the invention described hereafter provides for four such showers.

A furtherA object of the invention is to provide a` shower-bath in which one set of supply pipes and one drain is sufiicient for a four or more compartment shower.

A further object of the invention is to provide a shower bath having lalcentrai mixing chamber forhot and cold water for a plurality of bath compartments thus eliminating many parts that would otherwise be required, andV also lessening the first and maintenance cost. Y

A further object of the invention is to pro vide a circular shower divided into a plurality of compartments to eliminate rectangularcorners and form a construction which from its circular shape is self-cleaning.

In the drawing anneXedl Fig. 1 is a side view of the invention with one of the partitions removed, part being in section; f l g Fig. 2 is a top view; p Fig.Y 3 isa fragmentary side view of the Lmixing-fitting with parts in,L section, taken on tlie line 3-3 of Fig. 4; Figlli isa cross-sectional View taken on the line 4 4 of Fig. 3.

A tubular framework is comprised of four upright tubes 1 firmly embedded in a dished concrete slab, these uprights being surmount ed by an annular ring tubing'l. A standard 2, centrally located in this slab, forms with the tubes 1 a frame for the partitions l dividing the ensemble into four compartments 3.

The central hollow standard 2 is provided internally with a mixing-fitting 5 which cony sists of an annular cylindrical hot-water chamber 6 supplied by a hot-water pipe 7 screwed into the top-wall thereof, as shown. The cold-water chamber 8 is supplied by a cold-water supply-pipe 9 screwed into the upper end of a tube of the chamber 8, which tube is the bore of the annular cylinder 6. Four segmental mixingor temperingbhambers 10 surround the hot and cold waterl chambers 6 and 7 and are each provided with connecting valves 11 and 12 to the col-d and hot water chambers, respectively, said valves controlling the proportions of the water and one set of such valves being associated with each chamber. c

An internally-threaded aperture in the top of each temperingchamber 1() provides an outlet in which is screwed the discharge-pipe 13, which pipeleads upwardly through the central standard 2, outwardly through the standard, and then kdownwardly to spraynozzle 14,' one of which is positioned in each compartment. The central standard 2 is surmounted by a fitting 15 screwed thereon, through which the hot and col'd water-supplypipes 7 and 9 extend horizontally after a vertical rise through the central standard 2. Said horizontal extensionsof pipes 7 and 9 may be connected totwo of the vertical members of the tubular framework 1 and thence through the concrete slab to a sourcewof hot4 and cold water supply or the source of sup-k ply may come from above by connection with the fittings 7 and 9 or withthe 9 at any point desired. r c

It will be observed that two of the( upright members of the tubular framework 1 maybe utilized as hot and cold water-supplypipes and are connectedto the hot and Coldwater-1` pipes 7 and 9, respectively. The other two upright members are dead pipes and they are ture. Thepipes 7 9 and 16 extend into the litting 15 and are held firmly v by the setscrews 17. v u

,It will be further observed that the circular dished concrete or other material slab 19 which maybe formed on yan ordinary floor or the Hoor be thus constructed when new aids in drainage through apertures 18 at the foot of the central standard 2, and the waste water is disposed of through the concrete slab by means of the central cylinder in any manner desired. f Y In accordance with the provisions of the .pipes 7 and patent statutes, we have herein described the principle of operation of our invention, together with the apparatus which we now consider to represent the best embodiments thereof, but we ydesire to have it understood that the apparatus disclosed is only illustrative and that the invention can be carried out by other means. Also, while it is designed to use: the various features and elements in the combinations and yrelations described, some of these may be altered and others omitted and some of the features of each modification may be embodied in the others without interfering with the more general results outlined, and the invention extends to such use.

What is claimed as new is:

1-.- In a shower-bath apparatus, a central hollow column supported on a base, the column being provided with drainage-openings Lat its lower-end and the base being dished toward said openings, a series of spray-pipes projecting from the column at its upper-end, a frame supported on the base and arranged around the column, this frame embodying a pair of hollow uprights whose lower-ends are connected to water-supply-pipes, and means withinthe hollow column for controlling the admission of water to said spraypipes. Y

2; In a shower-bath apparatus, a central hollow column, a framework arranged around the column to form a plurality of com-partments, a spray-pipe extending from the topend of the column for each of said compartments, the inner-ends of these spray-pipes extendingdownwardly within the column, and a fittingenclosed within the column and having hot and cold water chambers connected respectively to the hot and cold watersfupply-pipes and also provided with valvecontrolled chambers connected to said spraypipes.

3; In ay shower-bath apparatus, a central hollow column, hot and cold water pipes extending into said column, spray-pipes extending into said-column, a fitting enclosed within said column and embodying a cold-water chamber connected tothe cold-water-pipe andv a hot-water chamber connected to the hot-water-pipe, amixing-chamber connectedt'o betlrsaid hotand cold-water chambers and also to one of the spray-pipes, and a valve accessible from the exterior of the column for controlling the, water entering said mixingchamber from said hotand cold-water chambers.- Y

4*. A shower-bath apparatus embodying a central hollow column .having a fitting attached toitsupp'er-end, a framework forming compartments around the column and having radialpipes connected to said fitting, two of said pipes serving respectively as hot-water and cold-water pipes and*y being extended downwardly in the tubular column, spraypipes radiating. from the column at a point ing compartments around saidV column;- hetV and cold water supply pipes as'sociatedlwith said column and having radially extending dischargepipes provided with spray devices, a' hot and cold water mixing chamber associated with said column and connected to the supply pipes, and valvesin each compartment 4.

associated with the mixingchamber for controlling the flow and the temperature of the waterydischarged from the spray devices,

6. A shower bath apparatus, comprising a central column having a fitting attached to its upper end portion, a framework extending around said column,radial partitions connected to the framework and forming a plurality ofmcompartments around the column, hot and cold water supply pipes extending within the columnand having upper radially extending discharge pipes provided with spray devices for discharging water downwardly in each compartment, Aa hot and cold water mixing chamber associated with the supply pipes, and valves in each compartment associated with the central column and thevmixin'g chamber for controlling the How. and the temperature of the water discharged from the spray devices.

7 In a shower bathapparatus, a central hollow column supported o na base, drainage openings, adjacent the,k lower end of the column, the base being of a form to direct water towards said openings, a frame supf ported on the base and arranged around the column and having partitions extending toward the column to form a plurality of compartments, a series of spray pipes projecting into the upper portions of the compartments, means supported by the celu-mn for lcontrolling the flow and temperature of the water discharged by the nozzles, and means for supplying hot and cold water to' the spray pipes In testimony whereof, we affix our signatures. f i, v HOWARD A.
